Hail in Leola · May 31, 2026
NEXRAD logged 104 hail signatures up to 2.5"; the estimated-size surface reached 1.5" aloft. At 2.5" — baseball — this is a severe hail signal associated with roof damage. Open it on the live map to see the swath over the streets.

Evidence / storm surfaces
How Leola saw the hail — from two instruments
May 31, 2026 · Leola, SD
Two instruments, one storm: NEXRAD logs the point signatures it detected overhead, while the estimated-size surface models how large the hail aloft could have grown. Agreement between them is not guaranteed — the gaps are where the model ran ahead of, or behind, the detections.

Radar-estimated hail size Surface resolved
Estimated size field Radar-estimated maximum hail size across the swath, modeled from radar aloft. It reflects the biggest stone the storm could support, which may differ from what actually fell.

The storm in context
Where May 31, 2026 sits in Leola's hail record.
This was Leola's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 3rd of the 7 storms we have logged here. Radar put the day's largest stone over Leola at 2.5" — the largest NEXRAD radar signature.
The May 31, 2026 convective day was bigger than Leola: the same system put hail over 637 other tracked cities, 61 of them in South Dakota. Nearest: Long Lake (11 miles northwest, up to 2.5"); Hosmer (17 miles west, up to 1.75"); Ipswich (19 miles southeast, up to 1.75").

Severe hail signal
What 2.5" hail means for Leola roofs.
Two-inch-plus hail is capable of puncturing shingles, breaking skylights or windows, and heavily denting soft materials. The strongest radar bands warrant prompt inspection, but neither the signal nor the footprint confirms damage at a specific address.

A storm day here is a convective day — it runs from noon to noon
UTC, so late-night hail is grouped with the afternoon storm that
spawned it rather than split across two calendar dates. Ground
reports are public-domain observations from the NOAA Storm
Prediction Center. Radar tells you where to look. Only an inspection confirms damage at an address. Last updated Aug 25, 2026.
